The Benefits of LED Lighting
Thinking about making the switch to LED bulbs? Find out more about LED technology and how LED lights compare to energy-saving light bulbs, halogens and old-style incandescent bulbs.

What are LED light bulbs?
LED lights have been hailed as the future of home lighting, as they use very little energy, claim to last a very long time and, unlike regular energy-saving bulbs, they are instantly bright when switched on.
Early LEDs were limited by high prices and relatively low light output, but the technology has developed rapidly in recent years, and you can now get bright, efficient LED bulbs that replace 100W old-style bulbs and look just like a traditional bulb. What’s more, prices are getting lower all the time. While the brightest bulbs can still set you back around £20, most cost less than £10, and the energy savings they will provide in your home make them well worth considering.
LED bulbs differ from traditional incandescent bulbs in the way they produce light. While old-fashioned incandescent light bulbs passed electricity through a thin wire filament, LEDs produce light through the use of a semi-conductor that emits light energy when an electrical current is passed through it.
This way of producing light is also different from regular energy-saving bulbs, which pass energy through mercury vapour to create UV light. This is then absorbed by a phosphor coating inside the lamp, causing it to glow.
LEDs are still the most expensive type of light bulb you’ll see in the shops, but they do have advantages over the other types of bulbs. LEDs are the most energy-efficient bulbs.
They use 90% less energy than traditional incandescents and can sometimes pay for themselves through energy savings in just a couple of months. So while the upfront cost might be high, you’ll notice the difference in your annual energy bills. By contrast, Compact Fluorescent Lamps (CFLs) use 60%-80% less energy than incandescents, while halogens use 20-30% less.
LEDs claim to be ultra long lasting – lasting for 25-30 years, depending on which one you buy and how you use it.
LEDs give out their light almost instantly when you flick the light switch, so you don’t have to put up with dim light while they get going.
Tests have found that LED and halogen bulbs work fine in low temperatures, whereas CFLs don’t.
